Description

ZW20 12F series outdoor high-voltage AC demarcation vacuum circuit breakers are high-voltage outdoor switchgear with rated voltage of 12KV and three-phase AC 50H z. They are mainly used to open and close the load current, overload current and short circuit of rural power grids, urban power grids and small power systems. Current. The overall structure of the product is a three-phase common box type, and the three-phase vacuum interrupter is placed in a metal box, with reliable voltage transformation performance and high insulation strength.
The operating mechanism of this series of products is a spring energy storage type, which is divided into two types: electric and manual. The circuit breaker complies with the regulations of GB1804, DL403, GB11022 and other standards,
No matter it is under normal use conditions or under fault conditions (especially open circuit conditions), as long as it is within the technical parameters of the circuit breaker, it can guarantee safety and reliability
It runs in the grid of the corresponding voltage level.
